Hi Tony,

There are a number of books on Ford EFI systems, for example:
<http://www.amazon.com/Ford-Injection-Electronic-Engine-Control/dp/083760301
3>
This book covers the different types of EFI systems used in Fords up to
about 2000, and explains the sensor terminology used by Ford. It's well
worth getting if you're considering the use of an OEM Ford system (or parts
of it) in an aftermarket setup. 

Ford computers are inexpensively available through eBay, and new ones can be
had from Ford Racing. It is probably easier to get a Mustang 5.0 manual
transmission computer than it is to rework an automatic-trans computer to
ignore the transmission codes. You can also buy aftermarket reprogrammed
engine control ROMs or reconfigurable ROM kits, but that is impractical
unless you have cheap access to an engine or chassis dyno.

As far as I know the Mk7 uses the same intake setup as the Mustang. This
won't fit under the Tiger cowl without major surgery to the heater box. The
only way I've figured you could get even close is to machine off the
thermostat housing and the block valley flanges, and then mount the manifold
back to front. This would position the upper part of the manifold two or
three inches further forward and may get you clear of the cowl. There are
lots of follow-on problems with that: you need to re-plumb the coolant
return to the radiator, rebuild the block valley flanges, and use a
distributorless ignition because the intake now interferes with the
distributor location. After all that you have to arrange for the upper
manifold to clear the hood - I have no idea if that's a problem or not, but
it would be pretty minor compared to making everything else fit. I have one
of the Explorer camshaft sensors that goes into the distributor drive - at
least that's a relatively available piece, and absolutely necessary for a
major mod like this. You could piece the rest of the ignition system
together with a bunch of EDIS parts and it would pretty much plug into the
EEC computer, or else you could run an aftermarket spark timing controller.

EFI that bolts on? Not this one... Lots of potential to make a cool one-of
though, if budget and time aren't a problem.
